What are the reasons for choosing Rotomolding Machine?

Inexpensive tooling: Because the tooling does not have to be subjected to high pressure, choosing the Rotomolding Machine allows it to be manufactured from low-cost materials such as aluminum. When only short production runs are required, the tooling requires less investment.

Production flexibility: Different parts can be molded simultaneously on a single machine. Some Rotomolding Machines have separate robotic arms for easy tool management; one mold may be scheduled for maintenance activities while other molds are in use.

What are the reasons for the popularity of Rotomolding Machine?

With proper design and setup, manufacturers and end users can benefit from

Uniform wall thickness: Consistent wall thickness, on all sides, edges and corners, increases the durability of the part.Rotomolding Machine achieves uniform wall thickness even when producing thick-walled parts through proper rotation speed and cooling cycles. Rotational molding produces thicker corners and edges than blow molding, which stretches the molten material in these areas.

Easy to produce double-walled parts: Double-walled parts are easy to fabricate, eliminating the need for secondary processes such as welding and joint fabrication. the Rotomolding Machine produces parts with seamless edges, eliminating stress points and thus increasing durability.

How does the Rotomolding Machine loading procedure work?

A quantity of polymer in the form of powdered resin is placed in a hollow mold and held tightly in place. The powdered resin must be finely dimensioned, homogeneous and dry to achieve good flow and to prevent bubble formation. The amount of resin loaded is one of the factors that determine the wall thickness of the part.

Hollow molds are made of cast aluminum or prefabricated steel plates and give the molded part its shape.

The release agent is a coating present on the inner wall of the Rotomolding Machine. It is used to effectively remove the molded part after cooling, as it prevents adhesion from the mold surface. The types of mold release agents are as follows.

Sacrificial coating: This type of mold release agent, usually silicone, will come off with the molded part when it is removed from the mold. Therefore, it is applied at the beginning of each loading process.

1. Semi-permanent coating: Semi-permanent mold release agents are commonly used in most industries. It lasts after a few cycles of heating and cooling of the polymer. It will be reapplied or refilled before it runs out.

2. Permanent coating: This type does not require reapplication of the release agent because it is permanently fixed to the mold surface. However, the permanent release agent layer can wear off due to scratching and mishandling. The most common type of permanent release agent coating is polytetrafluoroethylene (PTFE).
